Bests & Worsts Reviews from Amazon

I've used this app on almost all platforms (Apple, Android, Windows, etc) but this one is certainly the worst. I use it on my Fire phone and each time I tap the drop down notifications it freezes the entire phone and I have to restart it. Also, there's the fact that the chat bubbles do not function on any screen except the in-call screen... Because that's really user-friendly right? 🙇
